摘要
根据磁流变液的流变特性设计了一种新型半主动磁流变悬置结构,并简述了该悬置结构和工作原理。利用ANSYS电磁场分析模块对悬置结构内部磁场进行了有限元分析,研究了相同磁流变液悬置结构下,不同隔板材料对磁流变液悬置磁场分布的影响,并分别测试了采用不同隔板材料时磁流变液悬置的动特性。结果表明,所选择的低磁导率铝合金隔板材料可改善悬置性能;在磁流变悬置的设计过程中引入ANSYS的电磁场分析方法可行并具有一定的通用性。
According to the special properties of Magnetorheological Fluids （MRF）, a new semi-active structure of magneto-rheological （MR） mount is designed, structure and operating principle of this mount is outlined in the paper. FEA is made to the internal magnetic field of the mount using ANSYS electromagnetic field analysis module, which studies the effect of different baffle plate material on distribution of magnetic field of MR mount under the same MR mount structure, dynamic characteristic of the MR mount is tested with different baffle plate material. The results show that the low permeability aluminum alloy baffle plate material can improve performance of the mount; introduction of ANSYS electromagnetic field analysis method in designing MR mount has commonality.
